O045600100004 AUTHOR (M.K.BRUSSEL,J.H.WILLIAMS) O045600100005 INSTITUTE (1USAMIN) O045600100006 REFERENCE (J,PR,114,525,1959) O045600100007 HISTORY (19980630C) O045600100008 (19981125U) Last checking has been done. O045600100009 (20000426A) DATE is corrected O045600100010 SAMPLE Five Nuclide were Used in these Measurements- O045600100011 Fe-54, Fe-56, Ni-58, Ni-60 and Cu-65. O045600100012 Their Isotopic Composition was Determined by the Oak O045600100013 Ridge Laboratory at Their Time of Fabrication. O045600100014 Except For the Iron Target, which was 95% Fe-54, the O045600100015 Targets were Monoisotopic to Greater Than 98%. They O045600100016 Were Approximately 50 Mg/Cm**2 Thick.

O045600100021 The Telescope Arrangement was Used to Shield the Na-I O045600100022 Crystal from Charged Particles Emanating Elsewhere ThanO045600100023 In the Target. O045600100024 FACILITY (LINAC,1USAMIN) O045600100025 METHOD (SITA,BCINT) O045600100026 ERR-ANALYS The Errors For the Present Measurements were Found to O045600100027 Be Strongly Dependent Upon the Scattering Angle at O045600100028 Which the Measurement was Taken and Upon the ParticularO045600100029 Isotope Used As a Target. O045600100030 The Probable Error For the Experimental Unaveraged O045600100031 Absolute Cross Section Lies from +-6% to +-10% For O045600100032 Fe-54, Fe-56, Ni-58 and from +-7% to +-11% For Ni-60 O045600100033 And Cu-65. O045600100034 (EN-ERR).The Uncertainty is Reported by Authors. O045600100035 CORRECTION Background was Negligible at Angles Above 20 Degrees. O045600100036 Below 20 Degrees, Backgrond Corrections were Applied toO045600100037 The Data to Account For Protons Scattered from the BeamO045600100038 Collimating Slits or from the Mylar Exit Window of the O045600100039 Scattering Chamber. O045600100040 Another Correction Which was Applied to All the Data O045600100041 Concerned the Effects of Nuclear Interactions Made by O045600100042 Protons Entering in the Detector Crystal. Such O045600100043 Interactions would Tend to Decrease the Measured O045600100044 Elastic Scattering Cross Sections. Johnston and SwensonO045600100045 Have Investigated this Effect Carefully and have Come O045600100046 To the Conclusion That, For 40-MeV Protons, a 1.9% O045600100047 Correction Should be Applied to the Data to Account ForO045600100048 It. This Correction has Been Applied. O045600100049 REL-REF (R,,L.H.JOHNSTON+,J,PR,111,212,1958) Nuclear O045600100050 Interactions With Na-I.
